choroplethrZip返回"无法添加绑定"错误，即使我使用以下示例代码：
library(choroplethrZip)
data(df_pop_zip)
zip_choropleth(df_pop_zip,
state_zoom = "new york",
title = "2012 New York State ZCTA Population Estimates",
legend = "Population")
c$subtitle=subtitle:无法将绑定添加到锁定环境

新的ggplot版本(3.0.0(需要编辑choroplethrZip包的zip_chorpleth.R，正如包作者Ari Lamstein在https://arilamstein.com/blog/2018/06/27/choroplethr-v3-6-2-is-now-on-cran/:
在zip_clopleth.R中的最后一个函数(render_helper(后面添加一个逗号，然后插入以下代码：
theme_clean = function()
{
ggplot2::theme_void()
},
theme_inset = function()
{
ggplot2::theme_void() %+replace%
ggplot2::theme(legend.position = "none")
}
您需要该软件包的本地版本，可以从https://github.com/arilamstein/choroplethrZip.编辑zip_chorpleth.R，然后使用devtools包la:在本地安装代码
devtools::install_local('C:/Users/RickPack/Downloads/choroplethrZip-master')
